Classification of integrated circuits

There are many ways to classify integrated circuits, according to whether the circuit is analog or digital, it can be divided into: analog integrated circuits, digital integrated circuits and mixed-signal integrated circuits (analog and digital on one chip).

Digital integrated circuits can contain anything, with logic gates, flip-flops, multitaskers and other circuits ranging from thousands to millions in a few square millimeters. The small size of these circuits enables higher speeds, lower power consumption, and lower manufacturing costs than board-level integration. These digital ICs, represented by microprocessors, digital signal processors (DSPs) and microcontrollers, work using binary, processing 1 and 0 signals.
Analog integrated circuits have, such as sensors, power control circuits, and op amps, that process analog signals. Complete amplification, filtering, demodulation, mixing functions, etc. By using analog integrated circuits with good characteristics designed by experts, the burden of circuit designers is relieved, and there is no need to design everything from the basic transistors.

ICs can integrate analog and digital circuits on a single chip to make devices such as A/D converters and D/A converters. Such circuits offer smaller size and lower cost, but care must be taken for signal collisions.
